 Usually you would start several (3 or 5) master servers, then start the volume servers:
 
 ```bash
-weed master -port=9333 -mdir=./1 -peers=localhost:9333,localhost:9334,localhost:9335
-weed master -port=9334 -mdir=./2 -peers=localhost:9333,localhost:9334,localhost:9335
-weed master -port=9335 -mdir=./3 -peers=localhost:9333,localhost:9334,localhost:9335
+weed master -ip=localhost -port=9333 -mdir=./1 -peers=localhost:9333,localhost:9334,localhost:9335

 # now start the volume servers, specifying any one of the master server
